A paint spray booth is provided containing a plenum packed with a contact material for treatment of paint overspray generated during operation of the paint spray booth. The device comprises an anode, a hole blocking layer to separate an IR sensing layer from the anode, an organic light emitting layer that is separated from the anode by the IR sensing layer, and a cathode. Once the operator preferences are retrieved, the method applies the operator preferences including the preprocessing function preference to partially preprocessed raw image data. The rollers are operable to alter a position of the shaping rail relative to the bending rail. The control system is further adapted to selectively lengthen or shorten the legs to adjust the height of the support base. The charge pump includes an offset current circuit, which biases the charge pump to have a linear charge phase characteristic.
